After every meal, I am in the practice of brushing my teeth. I use a toothpaste recommended by my dentist, and I make sure to floss to remove any food between my teeth. I am also using a special kit for tooth whitening, something that is becoming more popular now. I visit my dentist every six months for a dental cleaning and checkup, and fortunately, my health insurance covers the cost. For most people, if you take care of your teeth, you won't get any cavities.
